This type of caisson is closed at the top and open at the bottom during construction and also the Working Chamber and Access Shaft are kept Watertight.
The Pneumatic Caisson necessitates a host of features required for the Dredging or Excavation process to be executed like the Air supply pipe, Power Supply Line for Power Tools, the Muck Pipe (to transport the Excavated soil to the Ground Surface), facilities for Concreting activities, Access shaft for the Construction Crew and for the transportation of Materials needed for the Excavation or Dredging Processes.

I. How is the Pressure maintained in the Working Chamber so as to ensure the surrounding Water does not flood the Working Chamber?
Answer: The pressure of the compressed air in the shaft is kept just higher than that of the water at that depth.

II. When the Access Shaft for the entry of crew is opened, the two different ends of the shaft are at different pressures which will result in an enormous load on the compressed air supply pipe since it has to keep the Water away from the Working Chamber.
